/**
 * Container for the parameters to the {@link com.amazonaws.services.ec2.AmazonEC2#createVpnConnection(CreateVpnConnectionRequest) CreateVpnConnection operation}.
 * <p>
 * Creates a VPN connection between an existing virtual private gateway
 * and a VPN customer gateway. The only supported connection type is
 * <code>ipsec.1</code> .
 * </p>
 * <p>
 * The response includes information that you need to give to your
 * network administrator to configure your customer gateway.
 * </p>
 * <p>
 * <b>IMPORTANT:</b> We strongly recommend that you use HTTPS when
 * calling this operation because the response contains sensitive
 * cryptographic information for configuring your customer gateway.
 * </p>
 * <p>
 * If you decide to shut down your VPN connection for any reason and
 * later create a new VPN connection, you must reconfigure your customer
 * gateway with the new information returned from this call.
 * </p>
 * <p>
 * This is an idempotent operation. If you perform the operation more
 * than once, Amazon EC2 doesn't return an error.
 * </p>
 * <p>
 * For more information about VPN connections, see
 * <a href="http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_VPN.html"> Adding a Hardware Virtual Private Gateway to Your VPC </a>
